HINGE.-

SPECIFICATION forming part of Letters Patent No. 727,653, dated May 12,1903. Application filed June 7, 1901. Serial No. 63,548. (No model.)

To all w/tom it "may concern:

Be it known that I, GEORGE A. LONG, a citizen of the United States, anda resident of Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inHinges, of whichthe following is a full, clear, and exact description,whereby anyone skilled in the art can make and use the'same.

Myinvention relates to the class of gravityoperated hinges; and theobject of myinvention is to provide a hinge, more especially applicablefor use in a telephone toll-collecting apparatus, which shallcertainlyinsure the automatic closing of the door of the case or box containingthe telephone set, and, further, to provide a hinge for such use theease of operation of which shall be such as to insure the automaticclosing of the door when it has been opened. A device by the use ofwhich these objects maybe obtained is illustrated in the accompanyingdrawings, in which- Figure 1 is a view in front elevation of a telephonecase embodyingmy invention. Fig. 2 is a view in elevation, on enlargedscale, of a portion of the door and case, showing my improved hinge.Fig. 3 is a like view, but showing the portion of the door raised 0 andhinge parts separated. Fig. 4 is a detail view in cross-section throughthe hinge. Fig. 5 is a view in central vertical section through thehinge.

My invention is illustrated and described 3 5 herein in connection witha box or case within which a set of telephone instruments is inclosedand forming a street-telephone apparatus, the inventionbeing especiallyadapt ed for use in connectionwith such an apparatus in which a coin isused for the purpose of opening the door to gain access to the tele-'phone and which is recovered after thedoor has been opened. In such anapparatus it is necessary that the door shall be readily closed afterthe instrument has been used,

and to this end it is essential that mechanism for closing the doorshall be provided which shall be positive in its operation at all timesand under any conditions of weather.

To accomplish this result, I have constructed a hinge of thegravityoperatedtype and have so arranged and constructed the parts thatthey are not liable to become inoperative in use.

In the accompanying drawings, the letter a denotesia 'post or standardsupporting a box or case b of astreet-telephone. This box or case isprovidedwith a door 0, having a handle a, by means of which the door maybe unlatched for the purpose of opening. This door 0 is provided,preferably at the back and near each end, with the socket member 01 ofthe hinge in the form shown, this socket member being preferablycastintegral with the door. A socket d is formed in'the socket member,the bottom (1 of the socket being formed on an incline or slope preferably extending in a straight line across the socket membe'r.-

A pintle member e issecured to the box or case, in the form shown beingcast integral therewith, this pintle member having a pin or pintle eextending upward and of a diameter to so fit within the socket d thatthe socket member at may be easily turned on the pin and will at thesame time completely inclose the working surfaces. The end e of the pinis formed on a slope or incline corresponding to that of the bottom d ofthe socket d and preferably extending in a straight line across the pin.This slope or incline on the bottom of the socket and end of the pin isso formed that the two surfaces lie flat against each other when thedoor is in the closed position.

It is important in providing an inclosing casing for the purposes hereindescribed that the door, as well as the main portion fof the casing,have a considerable weight; and of course it is imperative that thedoonbe let into and tightly fit within the casing in order to excludemoisture, sleet, and dirt. [It is also important. that with sucha heavydoor it should swing to closed position with as little jar as possibleand that a means be provided to prevent its rebounding. With theconstruction of binge herein described the end of the pintle and thebottom of the socket are in registering positions just as the doorreaches its closed position, and as the coacting surfaces are arrangedin the same plane transverse to the axis of the pintle and socket a sortof stop is formed, which cases the closing of the door and tends toprevent its rebounding.

It will be noted from the above construction that all of the bearingparts are inclosed and there is little chance of dust or dirt gainingaccess to the inclined surface between the bottom of the socket and pin,so as to injuriously affect the working of the device. It will also benoted from the above construction that the means for automaticallyclosing the door and for maintaining the engagement of the hinge membersare included in the socket and pintle--that is, a separate pin issocket.
